跟进此How to convert properly the xml radio into php array
的问题我有一个xml格式（输出），我想将其转换为PHP数组（输入）。但是我的代码不起作用，它只在我尝试运行它时显示我的数组的整个代码。
如何进行正确的转换？
我有这个带有单选按钮的xml：
<?xml version="1.0" encoding="UTF-8"?>
<Form xmlns="url" label="Home Visit Form" type="TextView" name="Form">
<Field name="ClientRelation" label="Client" value="Kamosi" type="TextView"/>
<Field name="ContactNum" label="ContactNum" value="12345678" type="TextView"/>
<Field name="Address" label="Address" value="tes" type="TextView"/>
<Field name="Landmark" label="Landmark" value="Pred dubem, za dubem" type="TextView"/>
<Field type="Delimiter"/>
<Field name="CP_RESULT" label="Cash pick-up result" value="CP_RESULT_PAID_TO_VISITOR" type="Radio">
<Item code="CP_RESULT_PAID_TO_VISITOR" label="Client paid to field visitor"/>
<Item code="CP_RESULT_PAID_THRU_PMT_CHANNEL" label="Client paid through payment channel"/>
<Item code="CP_RESULT_CLIENT_NOT_AVAIL" label="Client not available"/>
<Item code="CP_RESULT_CLIENT_CAN_NOT_PAY" label="Client can not pay"/>
</Field>
<Field name="CP_INFO_FROM_PAYEE" label="Notes" value="fgjjk" type="EditText" format="string"/>
<Field name="CP_PICTURE_RECEIPT" label="Receipt picture" value="Cash Pick-up 3400888888-CP_PICTURE_RECEIPT.jpg" type="Picture" format="string"/>
<Field name="CP_PICTURE_PLACE" label="Place picture (outdoor)" value="Cash Pick-up 3400888888-CP_PICTURE_PLACE.jpg" type="Picture" format="string"/>
</Form>

如何简单：
$xml = simplexml_load_string($xmlstring);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
